Earlier this morning I spoke about Facebook’s disturbing new “Big Cat” technology on ABC 702 Sydney, and here’s the audio.

Big Cat is the codename for an algorithm that can apparently detect with a high reliability whether your partner is having an extramarital affair, by analysing such things as their pattern of friend formation and communication, comparing their smartphone location with what they’ve said in posts — such as whether they’re really shopping or at the gym or on a work trip — as well as language cues, such as a tendency to avoid answering direct questions.

As I discuss with breakfast presenter Robbie Buck, however, this is a little more serious than sending someone some discount coupons on a likely hunch. Facebook had better get this right, given that confronting a partner about an alleged affair is a serious issue.

I’m hearing that the Australia test locations will be the Brisbane / Gold Coast nexus or, more likely, Adelaide, for reasons that I explain.

One thing we forgot to mention in the interview is the reason for Facebook’s codename: “Big Cat” is for catching cheaters. Oh dear.

Even before Google controversially demolished the privacy walls between its various products, we were already living in the total surveillance society. With every keystroke we are voluntarily telling companies, governments and heaven knows who else an awful lot about ourselves. Should we be worried about the uses to which this information could be put?

If you’re not yet at least experimenting with Twitter, the real-time social messaging service, you should be.

Suppress the corporate paranoia. It’s a lot easier than you might think. And while Twitter does get far more attention than its relatively small size might suggest — truly active Twitter users number perhaps 20 million globally compared with Facebook’s 750 million active users and counting — it punches well above its weight in terms of connecting with influential community members.

Twitter may not ever become the core real-time service used by the masses. Or if it does, it may only be for a few years. You only have to look at the last decade to see the then-leading MySpace surpassed by Facebook in 2008, just four years after Facebook was founded. Google’s launch of Google+ in June this year has generated plenty of speculation that the search and advertising giant’s foray into social networking will in turn wipe Facebook off the planet. Who knows?

There will always be some real-time social messaging service, however. Whether that’s Twitter as a stand-alone service, or whether we all end up using a real-time component of Facebook or Google+ or something that has yet to be deployed — none of that matters. The principles and practices of real-time messaging will doubtless end up being much the same.

Anything you might do with Twitter will be easy to migrate to any other real-time messaging system. The lessons you learn will carry across too.

In the cold, clear light of Saturday morning, what depresses me most about this whole episode is not that a supposedly-professional service would pull a trick like this and, when caught out, just smear PR bull over the top. It’s that they’ll probably get away with it, and imagine they handled it well.

“Social advertising”. It sounds so innocuous. But it isn’t. It means that simply by “liking” something on LinkedIn, or if you “take other actions”, they can use your name and photo in third-party advertising. Pricks.

Just what sort of mindset do LinkedIn’s executives have if they reckon this is an acceptable way to do business with people?

To me it indicates that they have no idea how people might react to discovering their face in someone else’s advertising. Or, if they do realise that, a disturbingly callous disregard for others, putting their business profits before their basic responsibilities as human beings.

If you’re a LinkedIn user and want to opt out of all this, go to where your name is displayed on the top right of your LinkedIn screen and click on “Settings”. Click on “Account” at the bottom left of screen, then “Manage Social Advertising”.

In 2005 Rupert Murdoch bought MySpace, as the orthography went, for USD 580 million. Yesterday he sold the operation, now branded Myspace or even just My_____, depending where you look, for a mere USD 35 million. Not exactly a profit.

The buyer was Specific Media, an advertising targeting company. One of the investors is musician and actor Justin Timberlake, although the size of his stake has not been revealed.

There’s now plenty of speculation about whether Myspace will build on its recent music focus, and how it’ll shape up against the monster that is Facebook and the new contender, Google+.

Yesterday I chatted about all this stuff with Lindy Burns on ABC 774 Melbourne. This time she got my name right.

A weekly summary of what I’ve been doing elsewhere on the internets. This week was mostly about the AusCERT information security conference on the Gold Coast, although a few things relating to the previous week dribbled through.

Podcasts

Articles

What a lot of articles we have this week! I was covering AusCERT as part of the ZDNet Australia team, and the Technology Spectator article was actually written the week before. There’ll be more AusCERT articles next week.

AusCERT 2011: Son of Stuxnet within a year: expert, ZDNet Australia. The source code for Stuxnet is out there. Security analyst Eric Byres reckons that’ll show everyone how to make sophisticated malware, and the “Russian business network” will be first off the rank.

Privacy is a commodity, for Technology Spectator, in which I bite the hand that feeds me by criticising the comment they use.

AusCERT 2011: Black hats and whitegoods, for ZDNet Australia. We’re creating the Internet of Things by turning everything into a network device. But when was the last time you heard an appliance manufacturer talking about network security? CBS Interactive’s Brian Haverty came up with the OARSUM headline.

Qld cops denounce ‘ethical hacking’, for ZDNet Australia. This headline is a bit of a misdirection. Ethical hacking is generally when the target has given permission, such as when someone is hired to do penetration testing. The kind of hacking games at black hat conferences, which is what Detective Superintendent Brian Hay was talking about, probably don’t fit into this category.

Media Appearances

I was asked to do a bit of trickery before Bennett Arron’s keynote at AusCERT. It didn’t go quite as planned. When Munir Kotadia produced the Day 1 Highlights video, he made sure that no-one forgot.

Corporate Largesse

I travelled to the Gold Coast for the AusCERT Conference on information security. My air fares, accommodation and breakfast were covered by CBS Interactive, ZDNet Australia’s parent company, as is normal for freelancers so that doesn’t count as largesse. AusCERT provided free conference entry, as is normal for any media attending, and that included meals and drinks at the social events. In the goodie bag was: webroot Personal Security and Mobile Security for Android from, erm, webroot; notebooks from webroot and Juniper Networks; PostIt-style thingies from Symantec; pens from RSM Bird Cameron, Citrix, Netgear and M86 Security; a Rubik’s Cube from WatchGuard; 3D glasses from SecurityLab; a yoyo from McAfee; and, via a voucher, an AusCERT conference t-shirt. I’ll have more to say about this later. I was also given a t-shirt by Sophos and a stubbie holder from Splunk.

[Photo:Sunrise over the Pacific, Surfer’s Paradise, taken from my room at the Crowne Plaza Hotel in 17 May. I didn’t really bother trying to take a good photo, it’s just a snapshot from my phone. Sometimes I wonder why I bother.]

The key lesson for me was that while LinkedIn is certainly useful for recruiters and job-hunters, it’s even more powerful when you think of it as a global database of professionals and their skills, experiences and connections, and use it for smart data mining — and by that I mean data mining that’s aware of the structure of people’s working relationships.

The other day I expressed my confusion over the point to LinkedIn. I now have the answer, thanks to an overwhelming number of comments. It’s a giant self-updating Rolodex. And it’s main use is recruitment — employees or freelancers finding work, or recruiters looking for staff.

That explains why it wasn’t making sense to me: I’m not in any of those categories. And when I am looking for work, well, I do media stuff. The people I’d want to contact are very public and easy to find. And I’m not wanting to “grow my business”. Fuck I hate that phrase.

That said, I can see that LinkedIn might be a useful tool for keeping track of the various people I interview for my media projects. Provided that LinkedIn allows me to add my own private notes to contacts — does it? — I’ll give it a go for a couple months and report back.

What also intrigued me is that having my comments posted on Hacker News led to a 2300% spike in traffic overnight — as well as a few people pimping their own internet start-ups. A different culture. Personally, I find the idea of drive-by commenting on a stranger’s website to promote your business to be… tasteless.

I agree with several people’s point that as a social network there isn’t much social in LinkedIn. People only checked back infrequently — such as when they were looking for jobs. I can see that LinkedIn is trying to encourage you to use the site more often, what with groups and stuff, but I got the feeling that this isn’t the way most people use the site. Am I right there?

[Update 30 March 2011:I’ve received a briefing session on LinkedIn, which I’ve now written about in Getting to grips with LinkedIn. I’ll close comments here and you can continue the conversation over there.]
